ELECTRICAL DISCHARGE MACHINING - A HIGH FUTURE NONCONVENTIONAL PROCESSING PROCESS
Electrical discharge machining is one of the most common processes for processing metallic materials. This process is characterized by the lack of mechanical pressure on the object that ensures the macroscopic location of the erosive agent. This scientific paper highlights a study based on experimental data processing as well as modeling the most important technological parameters for dimensional processing by electrical discharge machining with and without magnetic activation. In this context, the modeling and optimization of process parameters is approached, which can lead to the quality increasing of the processed surface, to an increase of the processing productivity and to a reduction …
Risk Assessment of Physical Security within a Technologized Knowledge Based Organization
The purpose of this scientific paper is to support the decisionmaking process on the risk management based on the results of an analysis and subsequently on the risks hierarchy. This assessment involves the comparison of the level of risk determined by the analysis with the risk criteria developed in the context of the establishment phase. This scientific paper on assessing and treating risks to physical security has been developed to identify, assess and quantify the associated risk in a technologizedknowledge-based organization. The basis of this study on the assessment and treatment of risks to physical security is to identify specific potential risks as well as the emergency response pr…
Experimental Research on the Cutting of Metal Materials by Electrical Discharge Machining with Contact Breaking with Metal Band as Transfer Object
The scientific paper presents practical research carried out by a mixed team of Romanian researchers from universities and the business environment. The research consists in applying the process of cutting metallic materials through electrical discharge machining with contact breaking using a metal band as a transfer object. The research was implemented with the help of a specially designed installation in the laboratory and subsequently all the necessary steps were taken to obtain the patent for it. Various metallic materials were cut using this process, but first of all, high alloy steels. In the global research conducted by the authors, active experimental programs and classic experiment…
